    90 Seadoo gts

    I bought a couple vintage seadoos cheap last fall
    i did a refinish and restoration on them as you can see from the pic

    I had them out on labour day weekend to see how they worked both seem to run well. Good compression seem strong for a little 580 cc

    my question is what does everyone recommend for oil in these. The previous owner basically put whatever he had in them. Is it a good idea to switch to a synthetic oil (Castrol Outboard or something) or do I just stay with a regular outboard 2 stroke oil
    ive had the starters off them and cleaned them up, cleaned the carbs checked fuel and oil lines. Previous owner had replaced implellors and sealing rings. Anything else anyone would recommend I do before I take them out this season

    Welcome to the site.

    Seadoo'd have oil in the jet pump, that should be changed once a season. You may want to do this if you have not done it yet.

    As long as it was stored / winterized properly, you really should not need to do anything else.

    As far as engine oil, I like Amsoil HP injector in the standard non PV SeaDoos.

    I tell people pick a good brand, and do not switch. It is not good changing oil brands all the time.
